[Cochleovestibular manifestations in coronavirus infection].

One of the main causes of the of the inner ear pathology is a viral infection including SARS-CoV-2 virus. On the other hand the psycho-emotional state of patients also affects patients with hearing loss, tinnitus and dizziness, and an increase in depression and anxiety was revealed during the period of self-isolation. Goal of our study was to analyze cochleovestibular pathology in patients with COVID-19.

The Use of Neural Network Modeling Methods to Determine Regional Threshold Values of Hydrochemical Indicators in the Environmental Monitoring System of Waterbodies.

The regulation of the anthropogenic load on waterbodies is carried out based on water quality standards that are determined using the threshold values of hydrochemical indicators. These applied standards should be defined both geographically and differentially, taking into account the regional specifics of the formation of surface water compositions. However, there is currently no unified approach to defining these regional standards.

[Bilateral vestibulopathy in elderly patients].

Balance disorders and recurring falls are the most frequent causes of medical treatment in old age. Chronic cerebral vascular insufficiency is considered to be the cause of instability in most of these cases, and its role in the development of postural instability in old age is likely to be greatly overrated. At the same time, the role of chronic peripheral vestibular disorders, by contrast, is underestimated.

[Labyrinth hydrops and its diagnosis].

The article deals with the basic theories of maze and labyrinth hydrops, which are often used in clinical practice for its diagnosis according to the world literature. Tonal threshold, suprathreshold audiometry, broadband thympanometry, ultrasound tests, test for determination of lateralization of loud sounds, dehydration test, extra-timbanical electrocochleography, method of registration of evoked vestibular myogenic potentials, study of vestibular function (video pulse test, caloric sample), CT of temporal bones with gadolinium, MRI, and other methods are considered. None of these study methods gives an accurate confirmation of the presence of maze hydrops.

[Tinnitus - current trends and prospects].

Tinnitus is described as the perception of any sound or noise in the absence of real acoustic stimulation. Numerous investigations have been tried for this potentially debilitating, heterogeneous symptom. The authors overview the current concepts of the management of the suffering tinnitus patients.
